Signature Compressor Online
Compression brings a heavy signature image down to a size portals accept. Upload once, choose a target, and download a lighter file. Pair this with pixel sizing when your form lists both requirements.

FAQs
How is this different from a general image compressor?
The flow is tuned for small signature uploads — quick KB targets and exam-related shortcuts — but you can still use a general compressor for photos.
Will compression change the colour of my ink?
Strong compression can flatten contrast. Use a well-lit scan and stop when the preview still shows clear strokes.
Can I compress to an exact KB?
You can aim for a maximum KB. Exact byte-perfect sizes are rarely required; staying under the limit is what portals check.
What about signature-only vs full A4 scans?
Crop to the signature area before compressing. Extra paper around the ink wastes KB and can fail dimension checks.
